New series of chlorinated aryl, N-tetra-O-acetyl-b-D-glucopyranosylated 1,2,4-dithiazolidines,viz. 3-p-chlorophenyl imino-,4-phenyl,5-tetra-O-acetyl-b-D-glucopyranosylimino-,3-p-chlorophenylimino-, 4-chlorophenylimino-, 5-tetra-Oacetyl- b-D-glucopyranosylimino-, 3-p-chlorophenyl-4[2,4-dichlorophenyl]5-tetra-O-acetyl-b-D-glucopyranosylimino-, 3-p-chloropheylimino-, 4[2,4,6-trichlorophenyl]-5-tetra-O-acetyl-b-D-glucopyranosylimino-1,2,4-dithiazolidines have been synthesized by the interaction of S-chloro-N-aryl isothiocarbamoyl chloride and 1-tetra-O-acetyl-b-D-glucopyranosyl- 3-p-chlorophenyl/ 2,4-dichlorophenyl/ 3,4-dichlorophenyl/ 2,4,6-trichlorophenyl-thiocarbamides in boiling benzene. The former has been prepared following the usual procedure, i.e. the controlled chlorination of pchlorophenyl isothiocyanate, while the latter by the interaction of tetra-O-acetyl--b-D-glucopyranosyl isothiocyanate and p-chloroaniline/ 2,4-dichloroaniline/ 3,4-dichloroaniline/ 2,4,6-trichloroaniline, respectively. The structures of the compounds have been established by conventional chemical transformation and IR, 1H NMR and Mass spectral analysis. The title compounds were screened for their antimicrobial activity against Gram Positive and Gram Negative microorganisms.
